Multi-Provider Payment Orchestrator
The Idea
A drop-in middleware that lets SaaS companies switch payment providers without rewriting code. Features automatic retry with backoff, webhook deduplication, and a unified reconciliation dashboard.
The Achievement
Processed $12K in simulated transaction volume during the 72-hour event. Zero failed payments during the final demo even when one provider was deliberately taken offline — failover worked seamlessly.
Tech Stack
Key Learning
"Distributed payment systems demand rigorous idempotency. One missed edge case = double charges. The event taught me to build failure-injection testing into the development loop, not as an afterthought."
Build bulletproof backend APIs
The same skills that delivered this hackathon under extreme pressure are available for your project. Fixed-price milestones, zero-bloat architecture, no dev-team drama.
